| 摘 要： | 介绍了两种典型的密封样品的去除吸附氦试验，吸附氦漏率的测试是在Inticon公司Pemicka700H型积累氮质谱粗漏细漏组合检漏仪上进行的。给出了试验数据、拟合模式和结果，进而分析了最新的美国军用标准MIL-STD-750—1／883J氯质谱检漏方法在降低被检件吸附氦漏率方面的不可检测性．并综合分析了这两项标准的其他问题，提出了全面改进的方案。

| Abstract: | Two kinds of typical removing absorbed helium testing for hermetic samples are introduced. The helium leak test is performed with Inficon＇s Pernicka 700H, and the test data, fitting mode and results are given. The undetectability of the helium leak test in the new Mil- Std-750-1/883J in terms of reducing the absorbed helium leak rate of the item-under-test is analyzed. The other problems of the two standards are analyzed, and the solution for improving the testing is presented. |
